This enforceable civil final judgment was issued in January 2028 by the United States District Court for the Southern District of Texas, Case No. 4:27-cv-00619, originating from authentic cross-border utility patent litigation filed by U.S. power equipment brand NOCO LLC against a Chinese electronic injection molding factory exporting infringing portable lithium jump starter power packs to Amazon.com, Walmart and AutoZone U.S. offline auto retail channels. The mainland Chinese manufacturing and R&D parent is anonymised as HengXin Electronic Technology Co., Ltd., a Zhejiang factory specialising in lithium battery pack assembly, safety equalisation circuit development and plastic shell moulding for automotive emergency starting power supplies. The plaintiff NOCO LLC holds two core issued U.S. utility patents: US10328808B2 and US11254213B2, covering intelligent overcharge protection circuit and multi-cell balanced discharge architecture under 35 U.S.C. §101–§133.
Starting March 2027, HengXin Electronic’s internal electrical engineering team fully reverse-engineered NOCO’s patented circuit layout, battery management logic and quick-clip conductive terminal structures without signing any formal patent licensing contract or paying royalty fees, mass-producing its HX-series jump starters at an automated Zhejiang production plant. To completely sever traceable links between U.S. auto parts cargo shipments and the Zhejiang factory and avoid treble enhanced damages stipulated under 35 U.S.C. §284, the group set up a wholly-owned Singapore private limited offshore trading shell named PowerSG Global Pte. Ltd.Every U.S. Customs entry declaration, Amazon/Walmart seller registration, ocean freight bill of lading, cross-border payment merchant ID and auto parts distributor product specification sheet exclusively used the Singapore shell’s legal identity; HengXin Electronic’s full Chinese corporate name was intentionally redacted, erased and excluded from all U.S.-oriented logistics, platform and commercial documents. This premeditated corporate veil evasion scheme was constructed to block multi-jurisdictional discovery and isolate all patent infringement liability from the Chinese mainland manufacturing parent enterprise.
Three systematic concealment tactics were deployed to hide the domestic infringing lithium equipment factory:
1. Register PowerSG Global Pte. Ltd. under Singapore ACRA corporate regulatory rules that permit undisclosed ultimate beneficial owners. All revenue generated from U.S. jump starter wholesale sales flowed into Singapore offshore corporate bank accounts, while the shell publicly represented itself as an independent Southeast Asian auto electronics importer with zero lithium circuit R&D or injection moulding production capacity within mainland China. Across 21 consecutive months of infringing export shipments, Singapore corporate registry databases contained zero publicly retrievable records linking PowerSG to HengXin Electronic Technology.
2. Execute sham independent hardware sourcing agreements falsely certifying PowerSG purchased all jump starter circuit modules and lithium packs from unrelated third Asian electronic component vendors. Internal cloud ERP production scheduling logs, factory CNC mould engineering drawings and Zhejiang office WeChat R&D meeting transcripts irrefutably proved HengXin held 100% equity of the Singapore shell, controlled all pirated patented circuit replication, batch production planning and U.S. auto retailer sales strategies, and manufactured every infringing jump starter unit entirely at its Zhejiang facility.
3. Recharacterise all U.S. marketplace revenue by labelling monthly offshore wire transfers remitted back to HengXin’s domestic Chinese corporate bank account as “lithium battery equalisation circuit algorithm technical consulting fees”, artificially reclassifying profits generated from patent-infringing automotive jump starter hardware sales as tax-exempt technical service income to obscure infringing profit cash trails from forensic accounting auditors and plaintiff patent counsel.
NOCO’s legal team first identified tens of thousands of infringing HX-series jump starter listings under PowerSG’s multiple brand aliases on U.S. auto goods wholesale portals in April 2027. Multiple formal cease-and-desist letters and patent infringement demand notices sent to PowerSG’s registered Singapore corporate secretary address were completely ignored. The Singapore offshore entity refused to disclose the actual Chinese manufacturing origin of the infringing jump starter equipment, forcing NOCO to launch cross-border discovery covering Singapore corporate registration records, Zhejiang factory server engineering design logs and transnational bank payment transaction histories.
After the Texas Southern District judge fully granted the plaintiff’s comprehensive cross-border discovery motion in September 2027, legal counsel obtained complete ERP server operation logs, Singapore offshore bank transaction trails, internal enterprise WeChat R&D meeting archives and original reverse-engineering technical blueprints, identifying multiple aggravating willful infringement factors entirely distinct from prior surgical instrument, household water filter and 3D sculpture patent/copyright cases covered in earlier materials. First, HengXin’s internal precision electrical R&D team fully reverse-engineered NOCO’s patented multi-cell equalisation main circuit assembly, extracted protected overcurrent and overheating protection chip parameter logic, and only modified trivial surface plastic rib layout positions to create superficial technical differentiation while retaining 99.1% of the original novel inventive combination claimed in both asserted utility patents. The court-appointed independent electrical forensic engineer confirmed literal infringement of 11 independent and dependent patent claims under 35 U.S.C. §271; trivial cosmetic plastic housing structural adjustments cannot eliminate direct manufacturing infringement liability for commercial automotive lithium jump starter hardware. The factory actively marketed these infringing jump starters to large U.S. auto supply chain distributors for massive wholesale profit, fully verifying the enterprise engaged in deliberate patent copying driven by commercial financial gain.
Second, HengXin’s senior R&D and factory management issued formal internal written standard operating protocols mandating automatic permanent deletion of all reverse-engineering technical comparison files, U.S. jump starter patent reference documents and plaintiff cease-and-desist correspondence from cloud storage servers every 38 days. Recovered server access audit trails verified engineering staff permanently erased terabytes of critical patent-related circuit design raw data immediately after receiving NOCO’s first batch of infringement demand letters, constituting spoliation of evidence under Federal Rule of Civil Procedure 37, an independently sanctionable civil violation. Binding Federal Circuit precedent in Halo Electronics v. Pulse Electronics establishes intentional destruction of material technical patent evidence creates a rebuttable legal presumption that erased records would validate the defendant’s full prior awareness of ongoing patent infringement.
Third, the enterprise maintained uninterrupted lithium jump starter injection moulding and U.S. ocean freight export shipments of infringing circuit-equipped power packs across six separate U.S. CBP IPR auto goods cargo seizures between May 2027 and August 2027, with the aggregate legitimate wholesale market value of all infringing jump starter units exceeding $4.9 million under official CBP consumer electronics IPR valuation standards. Following each border detention, the group merely registered new anonymous PowerSG wholesale sub-accounts on U.S. auto e-commerce marketplaces and rerouted cargo shipments through alternate Houston and Corpus Christi Gulf Coast seaports to resume distributing infringing jump starter hardware to American auto parts supply chains, demonstrating reckless disregard for U.S. federal patent statutes and cross-border digital intellectual property enforcement regulations.
The core legal dispute of this litigation centred on whether the Singapore PowerSG trading shell functioned merely as an alter ego of Zhejiang HengXin Electronic Technology Co., Ltd., enabling the federal court to pierce the corporate veil and impose full treble patent damages directly on the Chinese domestic manufacturing parent, even though HengXin’s corporate name never appeared on any U.S.-facing customs, logistics or wholesale marketplace paperwork. The judge applied a multi-factor alter ego test under Texas federal common law, confirming three conclusive factual grounds proving the Singapore offshore entity was exclusively established to insulate HengXin from U.S. patent legal liability:
1. Complete absence of separate corporate formalities separating the two entities: All PowerSG offshore operating expenses, food-grade lithium raw material procurement payments and executive management salaries were remitted directly from HengXin’s domestic Chinese corporate bank accounts without formal intercompany loan contracts or independent board resolution voting records. PowerSG maintained no standalone office premises, dedicated U.S. auto electronics sales staff or independent cloud server operational infrastructure within Singapore territory.
2. Total commingling of corporate assets: All U.S. auto parts marketplace wholesale revenue, offshore holding capital and domestic Zhejiang factory R&D manufacturing operating funds circulated freely between HengXin Electronic Technology and PowerSG Global Pte. Ltd., with zero strict asset segregation maintained throughout the entire U.S. automotive jump starter export operation cycle.
3. The sole primary business purpose of the Singapore offshore shell was to isolate HengXin’s domestic lithium circuit manufacturing operations from U.S. patent oversight and federal civil litigation, with no legitimate independent trade activity unrelated to exporting NOCO-patented infringing jump starter hardware to American wholesale market channels.
The court issued a binding alter ego ruling in November 2027, holding HengXin Electronic Technology Co., Ltd. and PowerSG Global Pte. Ltd. jointly and severally liable for all patent statutory treble damages, fully dismissing the defendant’s argument that the Singapore firm operated as an unaffiliated independent Southeast Asian auto electronics trade intermediary with no connection to mainland Chinese lithium circuit manufacturing factories.
In the official written final judgment dated January 12, 2028, the Southern District of Texas issued sweeping punitive equitable remedies grounded in 35 U.S.C. §284 treble damage provisions for willful commercial utility patent infringement, which authorise enhanced damages up to three times the baseline compensatory award. Core binding judicial holdings included:
1. Baseline compensatory damages of $3.68 million, elevated to a total treble damages award of **$11.04 million**, payable jointly by HengXin Electronic Technology and PowerSG Global Pte. Ltd. The court applied the maximum 3x multiplier after weighing the single-layer Singapore offshore concealment scheme, repeated disregard of formal cease-and-desist demands, large-scale intentional spoliation of critical patent circuit source data, sustained wholesale commercial profits derived from mass jump starter patent infringement and six separate CBP cargo seizures without any corrective compliance measures implemented.
2. Permanent nationwide U.S. automotive electronics import exclusion injunction under 19 U.S.C. §1595a directing U.S. Customs and Border Protection (CBP) to seize, forfeit and fully destroy all future portable lithium jump starter shipments manufactured or supplied by HengXin or its Singapore offshore shell arriving at any U.S. port of entry, with all product destruction costs borne solely by the two corporate defendants.
3. Permanent nationwide U.S. auto goods marketplace account termination injunction mandating Amazon Business, Walmart Wholesale, AutoZone B2B portal and all U.S. automotive electronics distribution e-commerce platforms to permanently disable every merchant account registered under PowerSG’s trade aliases, freeze all associated platform payment wallet balances, and block new commercial seller account registrations controlled by HengXin’s executive and beneficial ownership team for six consecutive years.
4. Full reimbursement of the plaintiff’s total attorney fees, electrical engineering forensic appraisal costs, Singapore corporate registry cross-border discovery expenses and offshore bank transaction record retrieval fees, an additional lump sum of $251,600 payable jointly by both corporate defendants pursuant to 35 U.S.C. §285 exceptional case cost-shifting legal standards.
5. Five-year offshore entity registration prohibition barring HengXin’s controlling executives from registering any new Singapore, Hong Kong, Malaysia or BVI anonymous offshore auto electronics lithium battery trading companies targeting the U.S. automotive aftermarket supply market, to prevent repeated offshore identity concealment tactics in future cross-border jump starter hardware export commerce.
The judge explicitly emphasised within the judgment that the premeditated complete erasure of the Chinese domestic lithium electronics manufacturer’s legal identity from all U.S.-targeted logistics, customs and wholesale marketplace documents constituted an independent aggravating factor justifying maximum treble damage awards, as the Singapore offshore corporate framework was constructed solely to obstruct patent holders’ capacity to identify, investigate and redress mass willful utility patent infringement originating from mainland Chinese precision electronic manufacturing facilities.
This landmark Texas Southern District federal judgment establishes enforceable compliance benchmarks for all Chinese lithium battery pack, automotive emergency power and precision circuit manufacturing factories exporting patent-protected consumer automotive hardware to the United States, Sweden, EU member states, Switzerland, Spain, Netherlands, France, Germany, Türkiye and India: First, Singapore, Hong Kong, Malaysia or BVI offshore holding or trade subsidiary structures cannot be deployed to deliberately omit or redact the full legal identity of the domestic Chinese manufacturing parent on all U.S. customs filing, ocean freight, wholesale marketplace registration and cross-border payment export paperwork for the purpose of evading U.S. patent liability. Federal courts will readily pierce alter ego corporate veils when offshore shells exist solely as liability-shielding front operating vehicles for mainland infringing electronic manufacturing factories. Second, systematic concealment of domestic manufacturing source identities, intentional mass deletion of patent-related circuit engineering design evidence and repeated refusal to comply with formal patent cease-and-desist mandates will trigger maximum treble enhanced damages under Title 35 U.S.C., vastly exceeding financial penalties for minor or unintentional patent violations within cross-border automotive electronics trade. Third, full transparency of domestic corporate ownership, manufacturing geographic origins and complete patented circuit hardware supply chain documentation must be preserved for all automotive equipment exports bound for the U.S. market. Deliberate misrepresentation of corporate entity identity to U.S. federal agencies, CBP electronics enforcement divisions and commercial auto wholesale marketplaces creates a rebuttable legal presumption of willful patent infringement under §284(c) of the U.S. Patent Act.Chinese lithium electronics manufacturing enterprises simultaneously launching product lines across EU and non-EU overseas jurisdictions face parallel patent compliance risks under regional EU consumer goods patent directives; anonymous single/multi-layer offshore shell concealment frameworks will similarly result in elevated damage awards within European national IP courts and EUIPO administrative opposition proceedings for automotive lithium hardware products.
